I see what you mean, and was missing this because mostly using the menu 
which already proposes other applications (and therefore has no way to 
select a default application).

There seems to be a caveat though: I cant seem to be able to eventually 
change that to something else. i.e. if I select the "default" checkbox 
for an application, then I do open with other application, select a 
different one and also select the "default" checkbox, the former 
application is kept as default?

On the other hand if I edit by hand $HOME/.config/mimeapps.list and 
change the first instance of that mime type (i.e. its .desktop entry), 
that seems to work.
